A healthy young male is brought to the emergency department following a motor vehicle crash. His vital signs are a blood pressure of 84/60, pulse 123, GCS 10. The patient moans when his pelvis is palpated. After initiating fluid resuscitation, the next step in management is:

placement of a pelvic binder

The most important, immediate step in the management of an open pneumothorax is:

placement of an occlusive dressing over the wound

A 22-year-old female athlete is stabbed in her left chest at the third interspace in the anterior axillary line. On admission to the emergency department and 15 minutes after the incident, she is awake and alert. Her heart rate is 100 beats per minute, blood pressure 80/60 mm Hg, and respiratory rate 20 breaths per minute. A chest x-ray reveals a large left hemothorax. A left chest tube is placed with an immediate return of 1600 mL of blood. The next management step for this patient is:

prepare for an exploratory thoracotomy

A 22-year-old man is hypotensive and tachycardic after a shotgun wound to the left shoulder. His blood pressure is initially 80/40 mm Hg. After initial fluid resuscitation his blood pressure increases to 122/84 mm Hg. His heart rate is now 100 beats per minute and his respiratory rate is 28 breaths per minute. A tube thoracostomy is performed for decreased left chest breath sounds with the return of a small amount of blood and no air leak. After chest tube insertion, the most appropriate next step is:

re-examine the chest

A 22-year-old man sustains a gunshot wound to the left chest and is transported to a small community hospital no surgical capabilities are available. In the emergency department, a chest tube is inserted and 700 mL of blood is evacuated. The trauma center accepts the patient in transfer. Just before the patient is placed in the ambulance for transfer, his blood pressure decreases to 80/68 mm Hg and his heart rate increases to 136 beats per minute. The next step should be to:

repeat the primary survey and proceed with transfer

What findings in an adult is most likely to require immediate management during the primary survey?

respiratory rate of 40 breaths per minute

A 39-year-old man is admitted to the emergency department after an automobile collision. He is cyanotic, has insufficient respiratory effort, and has a GCS score of 6. His full beard makes it difficult to fit the oxygen facemask to his face. The most appropriate next step is to:

restrict cervical motion and attempt orotracheal intubation using 2 people

A trauma patient presents to your emergency department with inspiratory stridor and a suspected c-spine injury. Oxygen saturation is 88% on high-flow oxygen via a nonrebreathing mask. The most appropriate next step is to:

restrict cervical motion and establish a definitive airway

A 32-year-old man's right leg is trapped beneath his overturned car for nearly 2 hours before he is extricated. On arrival in the emergency department, his right lower extremity is cool, mottled, insensate, and motionless. Despite normal vital signs, pulses cannot be palpated below the right femoral artery and the muscles of the lower extremity are firm and hard. During the management of this patient, what is most likely to improve the chances for limb salvage?
